So, I remember reading this one light novel?? That got adapted into a manhwua years ago.
I remember key details like the mc being a girl but had to pretend to be a guy or else she will be killed. It was a regression(?) Or another soul the got in her body, a god tier level cultivator in their past life.
She saved her family in the brink of ruin and there was a magical beast(?) that follows her around. She met a guy in the valley while she was training. I remember they lived together for a while in a cave. The guy was actually the crown prince and was cursed with his soul broken. Unbeknownst to them the mc had a fragment of his soul in her bracelet, I forgot how she got it.
I hope someone remembers or know this T_T
